However, the right reader spinning threshold may vary from one system to another and among the different architectures. This patch adds a new kernel boot parameter to modify the threshold value. This enables better tailoring to the needs of different systems as well as for testing purposes.It also means that those systems could very easily be incorrectly tailored.(and worse case scenario: reboot, is obviously a terrible way to get ridof any issues). I very much disagree with exposing this sort of core stuff,it should work well for everyone out of the box, not relying on users to properly configure this. Thanks, Davidlohr
I also have some concern about exposing this kernel parameter as it will be hard to tune. That is why I put it at the end to gauge the opinion of others. I will leave this out when I send out the next version.
